I've looked closely at the Micronas IC while ago, and it seemed
attractive for several reasons. I even put the schematics together,
however it didn't make into the prototype. So I can't comment how well
it works in the reality.

hello all,
I am designing an application where I have an MP3 (music) decoder
along with a speech encoder (not music quality). The encoder should
preferably be able to store a file in audio format on a SD-card.
I am looking to find a single chip / chipset with minimal number of
components for my design.
I did find some encoder/decoder chips from a few manufacturers
(Micronas MAS3587F, VLSI VS1001K, ST STA 013), but I couldn't find a
"that's it" one. Has anyone used any of these chips before? Any
comments / suggestions on the pros/cons of some currently available
chips would be most welcome.
thanks,
